A

MCQ: Dimensions of strain are

1. [L]
2. [M] [L]-1 [T]-2
3. [L]-1
4. It's a dimensionless quantity

D

MCQ: At ‘yield point’ of a copper wire

1. the load hasn't exceeded the elastic limit yet; so, Hooke's law applies
2. the load has already exceeded the elastic limit and the material has become plastic
3. even the plastic stage has passed and the wire has snapped already
4. Like Brass and Bronze, Copper has no yield point

B

MCQ: Substances that elongate considerably and undergo plastic deformation before they break are known as

1. brittle substances
2. breakable substances
3. ductile substances
4. elastic substances
